Abstract

If burning a gallon of ethanol emits less greenhouse gas or GHGs (CO2, primarily), than the gasoline it replaces then it has a smaller carbon footprint than gasoline. Actually, it is the amount of fossil CO2 emitted that matters, because CO2 from fossil fuels represents "new" carbon in the atmosphere, whereas the CO2 released by corn ethanol is recycled atmospheric carbon.
